Application fi1ed September 28, 1908. Serial No. 455,15aREIggUEE To allwhom it may concern:

Be it known that I, THOMAS G. PLANT, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Lasting-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts. I

This invention relates to machines for lasting boots and shoes, and more particularly to machines of the bed lasting class employing wipers for the lasting operation.

The invention will be best understood by reference to the following description when taken in connection with the accompanying carriage and other illustration of one specific embodiment thereof, while its scope will be more particularly pointed out in the appended claims.

While many features of the invention may have general application to lasting machines of widely varied types and of materially different construction from the machine herein disclosed,'for the sake of illustrating one concrete embodiment of the invention, the same is shown as applied (Fig. 1) to a well-known type of bed lasting machine, to which general type, moreover, the invention in certain of its aspects has particular and I a the-overhanging trackway 6 is a supportlg carriage for the heel lasting head 7. The eel lasting wipers, indicated at 8, are oenedand closed by the wiper lever 9, and re angularly adjustable longitudinally to BCOIIIIIlOdZttB the spring of the last by means ntrolled through the hand wheel 10 and ljustable transversely to accommodate the 11 of the last by the hand wheel 11. Simirly, at the toe lasting head for opening 1d closing the toe wiper lates, represented 12, there is provided tie wiper lever 13, id for their angular adjustments lon itunally and transversely the hand wheels and 15 respectively. At the heel lasting carriage there is proded a heel pin 16 sustained (see Fig. 5) by e heel post 17, the latter adjustably sup- |rted as by the underlying inclined cam wedge 18. In the employment of the mame the jacked shoe, designated at S (Fig. is elevated on the said wedge by means ntrolled through the hand wheel 19 (Fig. and its heel retracted into the heel band the same movement of the hand wheel wing to draw the carriage toward the cenof the machine where 1t is positioned by gagement between the pivoted latch 21 d the stationarycatch 22 on the frame of a machine. The toe of the last, when thus sitioned, is held over a toe pad 23, on the post 24, vertically slidable in the bracket on the toe lasting head. The toe post ts upon a hinged table 26 controlled by an lerlying cam and cam shaft. The details the camshaft are not herein shown, but y be of a construction well-known in ma nes of this type adapted, as well underod, when the shoe has been positioned as cr1be,d, to be set in operation by pressure the knee lever 27, to raise the toe pad 23 just the shoe and, at the same time, clasp heel band about the heel of the shoe. 2 hold-down 28 being then drawn down inst the upturned sole of the jacked shoe means of the foot lever 29, the shoe is Jed in readiness for the lasting operation. or the leather has been wiped over the in-' and fastened. thereto, the knee lever 27' is ;sed again to turn the cam shaft, causing toe pad to be drop ed, the hold-down ened and the heel asting carriage reed and movedback to its outer position lg the track 6 which carriage movement, urn, causes the heel band to open and the post to drop. These movements are understood in lasting machines of this and the specific. constructional details he mechanisms reducing them require Further illustration or explanation save far as they may incidentally relate. to rovements herein subsequently described. eferring first to the construction of the and too lasting heads and the devices for )ting the wipers to the roll or swing of the last, these will be best understood by reference to the heel lasting carriage and particularly to Figs. 4, 5, 7, 8 and 10. For the angular longitudinal wiper adjustment, the heel lasting carriage or base 7 (Fig. 5), which tracks upon the rollers 32, is provided at each-side with upright ears 33 between which is hinged upon the transverse rod 34 the intermediate support or saddle 35. The latter comprises longitudinal arms connected by front and rear transverse members 36 and 37 respectively, which latter are formed to present curved segmental guideways (Figs. 5, 8 and 10) and afford a sliding support for the correspondingly fashioned flanged supporting portions 38 and 39, which depend from the wiper carrying support 40. The wiper support 40 can be an ularly adjusted about .a longitudinal axis through sliding movement of the segmental supporting flanges 38 and 39 on their curved guideways, which movement-herein is imparted (Fig. 8) by a sliding rack block 41 located within a chamber 42 in the rear transverse saddle member37, the block being provided on its upper face with teeth meshmg with correspon ing teeth on the under face of the supporting flan e 39. The rack block may be moved in eit er direction from the position shown in Fig. 8 to tip the wiper support by turning the hand wheel 11 and the attached screw 43, the latter having threaded engagement with the walls of the saddle. The screw has a reduced ortion ada ted to turn freely in the block, ut longitu inally fixed therein, by the collar 44 working in a transverse slot in the block.- The supporting segments 38 and 39 are held in engagement with the guideways by flanged gibs 45 and 46 respectively, which overlie the curved upper faces of the flanged supports but are bolted to the uideway segments 36 and 37 respectively. %or the angular adjustment of the wiper carrier longitudinallyand about the hinge 34 the flanged gib 46 is provided with a bracket 47 (see Figs. 5 and 7 ),which has threaded engagement with the vertical adjusting screw 48, the latter provided with the hand wheel 10 and having a combined swivel and pivotal connection, as at 49, to the carriage 7. It will be noted that the forward segmental guide 36 and its gib 45 provide a bearing for the sidewise rocking wiper-su port extending close to the heel band an rying cams 50.

well under the sliding wiper car- The construction of'the devices for adjusting the wipers on the toe lasting head is substantially the same as that described in connection with the heel lasting head and will be readily understood from the drawin s without further explanation.

assing now to the construction of the wipers for the heel lasting head, these are carried on the usual wiper carrying plates or cams 50, which latter are secured by means of the rearwardly extending links51, Fig. 7, the cross-bar 52 and the tail piece 53 to the wiper operating lever 9, the latter (Fig. 7) pivoted to an arm 54; secured to the Wiper support 10. As usual, the Wipers are given a combined advancing and closing movement by the operating lever through the provision of curved cam slots 55 (Fig. 18) in the wiper plates with which are engaged rollers 56 carried on fixed studs,

the latter connecting the underlying wiper carrier and the overlying plate 57, be tween which the wiper plates are adapt-- ed to slide. While the wipers are usually arranged in symmetrical relation to the cams so that they close in from the same position relatively to the center line of advance, in lasting shoes where the swing of the last presents wide variations between rights and lefts, so that the inside shank of r so the last presents a deeply retreating face, it is often desirable to shift the inside wiper and swing it inward so that it will start to close farther in toward the center line of the head. One feature of the present invention lies in the provision of means for quickly adjusting either or both wipersfor different swin of the lasts, as, for instance, for rights or le ts. Various ways of securing this ad justment may be employed, but herein a wiper seat is provided (Figs. 18 and 19) on the under face of each wiper cam 50 by means of a beveled lip or shoulder 58 which underlies the beveled edge 59 of the wiper plate 8. The bevelededge of the plate and the li against which it fits, as viewed in plan {Fig 18), are curved preferably about the center of curvature of the cam directing slots 55. Each cam carrier is provided with studs 61 and 62 which engage curved positioning slots 63 and 64 in the corresponding wiper, the said slots having the same center of the curvature 60, so that the wipers may, if desired, either or both be adjustably swung on the cams about the point which coincides with the center of opening and closing movement. Each wiper plate is held adjustably fixed on its carrying cam by any suitable means such, for example, as the down turned locking pin 65 which engages a suitably shaped slot 66 in the outer edge of the wiper plate to hold the latter rigidly fixed. The pin, however, is carried by an arm 67 pivoted at 68 upon the wiper carriers and provided with the handle 69 and the removable positioning pin 70, which latter may be inserted in any one of several openings 71 in the wiper carrier to variously fix the position of the locking arm. With the positioning pins in the outer one .of the openings 71 (as shown in Fig. 18), the wiperplatesare held in their normal positions symmetrically arranged relatively to the central plane of the head. and with their inner edges in contact.. By withdrawing its positioning pin 170 and turning its locking levers 67 to a different position, however, either wiper may be swung inwardly, as, for example, to the position shown by dotted lines in Fig. 18, thereby causing it to start and finish its closing movement nearer the center line of the last.

In the disclosed machine there are provided, in addition tothe wipers, auxiliary lasting devices which act to increase the draft on the stock when wiped over the last, as well as to direct the draft inward over the shank and rearward toward the center of the heel seat, such auxiliary devices also herein preferably being employed to prevent the slackening of the stock when the wipers are backed off and partially withdrawn preparatory to applying the fastening. Herein the said auxiliary devices comprise (see Figs. 5 and 15) pairs of grippers 72 for increasing and directing the draft on the stock at the side of the heel near the shank, and additional grippers 73 for increasing the draft at the end or rear of the heel. Both pairs are mounted upon the supplemental head 74, hinged by the rod 75 to the heel lasting head so that they may be thrown up out of the way into the position shown in Fig. 5. The grippers are provided with down turned lips presenting gripping means, such as the points 76 and 77 respectively, which, when the head is turned down (Fig. 13) are adapted to penetrate and positively engage the stock in front of the working edges of the wipers and to be moved in and over the last (Fig. 14) in advance of the wipers. The side grippers 72 are removably bolted. or screwed to the ends of fingers '78, provision being made for adjustment to accommodate different thicknesses of stock, by interposing one or more removable shims 79, and for longitudinal adjustment to change the reach of the grippers toward the shank of the last by providing a plurality of screw holes in the fingers. The fingers 78 are pivotally secured to and above the head 74 by means of studs 80 and have their rearwardly projecting ends drawn together by springs 81 which tend normally to spread apart the side grippers, as shown in Fig. 15.

The heel lasting grippers 73 are carried on arms 82 which have sliding movement between the head 74 and the underlying plate 83 (Figs. 1 and 5) secured thereto. When the heel grippers are advanced, as will be described, their movement is directed by rollers 84 carried by the rear ends of the arm 82 and engaging curved guideways 85 formed in the head, the guideways being located in such relation to: the directing slots for the wiper cams that the heel lasting grippers execute a closing-in movement conforming to that of the wipers. The heel lasters are normally retracted to the open position shown in Fig. by the spring 86 having oneend fixed to the head and the other connected in common to the pins 87 fastened one to each of the arms 82.

When the supplemental head 74 is turned down to use the lasters, the grippers 6 are guided into position (see Fig. 13) to overhangthe front edge of the Wipers by con tact between the outer beveled edges of the down-turned gripper lips and the upright horn-shaped abutment 88 presented by the locking lever 67 on each wiper carrier.

Likewlse the grippers 73 are positioned to overhang the wiper edges b guiding contact with the beveled top e ges of the upright pins 89 carried each by one of the wlper plates see Figs. 5 and 18). In this position of t e grippers, any closing-in movement of the wipers will be accompanied by a corres onding closing-in movement (see Fig. 14 of the grippers due to the pressure of the abutments 88 against the side grippers and the pins 89 against the heel ippers, the said pins and abutments acting as the means for advancing the grippers over the last.

Means are provided to depress the gri pers at will and cause the points 76 and $7 to penetrate and grip the stock. This is accomplished by provlding on the head 74 a cap late 90 adapted to slide lengthwise the head? The cap plate is provided with shoes 91 underlying the edges of the head, which shoes present, each on its upper face, an in- :line adapted to engage with the under side 3f an overhangin ear 92 (see Fi 7) the latter bolted to t e late 57 on t e. wiper support, so that, wlth the lasters turned lown and the ca plate advanced, thein- :lined shoes will orcibly depress the entire ;upplemental head about 1ts hinge and :ause the laster points to dig into and take iold-of the stock. To advance the sliding :ap for the depression of the grippers, the :ap has jointed attachment at 93 (Figs. 5 tIl'd 13) to the hand lever 94,'the latter pivvted on the bracket 95 which is secured to he head 74.

Means referably are provided and assoiated wit the grippers to position or level he shoe with respect tothe lasting devices .nd acting also to prevent such an-approach f the gripper-teeth to the insole as might ause them to penetrate too deeply and tear he stock. Such means are herein compreended in a down hold foot comprising the djustable head 96 carried by the threaded in 97 depending from the bracket 98. The Ltter is su ported by an arm 99 on the suplemental ead between the lasters, so that 1e down hold may be depressed against 1e upturned insole at the heel seat and beond thorange of wiper action. By adisting the head 96 on the pin the penetra- .Fig. 13. The hand lever 94, bein The tion of the gripper into the stock may be re ulated. j

n the use of the heel lasters, the head having been swun down, the lasters assume the relation to t e wipers representedhin t on swung over to the position shown in ig. 14,

-causes the teeth of the lasters to ip the stock and, when the wipers are a vanced, move from the osition shown in Fig. 13 to that shown in ig. 14. In executing this movement the heel lasters advance and close in substantial correspondence with the wipers supplementing the frictional hold of the latter. The side lasters, not only likewise increase the draft on the stock, but being pivoted on the supplemental head and projecting (Fig. 13) well beyond the for-- ward limits of the wipers, engage portions of the stock not initlally touched by the wi ers, which portions, however t1see Fig. 14 are drawn or held back into t e ran e of wiper action at the close of the wi er a Vance. With end wipers, as ord inarily used, the draft upon the stock, while inward over the insole, is also forward, thistending to slacken the stock overlying that portion of the last not reached by the wipers until near the close of their movement, as,for example, adjacent the insideshank portion of the shoe. Since the side gri pers have a closing-in movement only, while the wipers both close in and advance, the side grippers act to draw the stock relatively toward the advancing wi ers, preventing the forward draft, due to t e advance of the latter, from slackening the stock over the fore portionsof the heel seat. Thus, through the use of the auxiliary lasters, the stock from all sides of the heel, including the. inside concaved portion of the shank, can be drawn in snugly toward and over the heel seat and can be broken down by the advancing wipers. Having wiped in the stock as described, the operator may now return the wipers to a position near the edge of the 1nsole reparatory to applying the fastening.

depression of the lasters, due to the cam plate 90, causes them to remain fixed on the retraction and opening of the wipers, preventing such wiper movement from being accompanied by any slackening of the stock. With the wipersRt-racted, the lastin lever 94 may be swung back to release the lasters and the head 74 raised to permit application of the fastening.

In the case of lasts having an extreme swing, it will often be necessary to adjust the grippers so that the movement of the inside gripper, like that of the inside wiper,

shall be started nearer the center line of the.

last. While such adjustment might be independent and separate, herein it is made automatically consequent on-the adjustment of the wiper plates for, with either of the latter shifted to one side of its normal position, when the head is depressed, the corresponding lasters will still find their proper positions by engagement with the abutment 88 and pin 89 and lie closely adjacent the active edges of the wipers, as shown in Fig. 13. The beveled top of the pins 89 and of the horn 88 is so shaped that the lasters are correctly positioned and properly advanced in whatever position of adjustment the wiper plates may be placed.

Referring now to the heel band 20 for the heel lasting head, the same comprises (Figs. 5 and 11) a pad or facing of leather or other suitable material supported by the flexible sprocket chain or carrier 100. The latter is suitably supported by 'the rearwardly directed pin 101 on which it is hinged by the link 102 so as to rock slightly for adaptation to the last. The pin is adjustably held in the Wiper support by the set screw 103. The ends of the'pad carrier are jointed t0 the pad supporting fingers 104 (see Figs. 5, 7, l1 and 12) which are pivoted to the ends of the pad supporting arms 105,

the latter being slidably mounted in the wiper support 40. The supporting arms are advanced to clasp the pad about the heel by means of the connected cross bar 106, the latter rigidly secured, as by the stud 107 and pin 108 (Fig. 11), to the sliding actuating bar 109. The actuating bar is connected to be moved by the cam shaft of the machine through suitable connections, such as the spring 110 and lever 111, the latter moved 'by the plunger rod 112 actuated by a cam as is customary in this type (not shown), of machine. The cross bar 106, being rigidly fixed on the actuator bar 109, the sliding arms are advanced equally and together. Means, however, are provided to cause the arms to turn to one side or the other, if necessary, to permit the pad to conform to the swing of the last. To effect this, the studs 113, which connect the arms to the cross barywork in slots 114 and each arm 105 fashioned to slide on a guiding block 115, the latter pivoted to turn on the wiper support 40, but secured beneath the same to a rearwardly projecting arm 116, which has an end contacting with the inclined face 117 of a wedge bar 118. The latter is secured to the under face of the cross bar 106 by the stud 107, but is permitted sliding 'movement lengthwise the bar by provision of the slots 119 and guide rollers 120 (Fig. 12). As the cross bar is advanced, the wedge acts to turn the guidingblocks 115 and.

swing the supporting ends of both arms 105 inwardly to clasp the ends of the pad about the last. Springs 121, connecting the lower endsof the roller studs and depending pins 122 on the ends of the arms 116, normally tend to keep the wedge central and the band symmetrical relatively to the axis of the supporting arms the head. If the heel band, however, re-

the last, the resistance to the advance of the wedge on one side or the other causes it to slide crosswise and turn the guiding blocks unequally to give a differential swing to and automatically adapt the pad to the heel.

After the shoe has been jacked, as previously described, it. is usual to provide means such as the elevating rod 122 to press the last up against the wipers. The rod herein is elevated bythe foot treadle 123 (Fig. 1) to cause the upper end thereof (Figs. 4- and 5) to engage with the overlying lateral horizontal strai ht ledge 124 on the elevating wedge 18 and thereby lift the heel post and last. To permit this the wedge 18 is pivoted at 125 to the heel last-ing head on the forwardly adjustable support 126, the forward end of the cam being yieldably supported by the preferably light spring 127. The wedge may be adjusted lengthwise the carriage to vary its lifting effect on the heel post by the segmental pinion 125", meshing with a rack 126 on the under side of the wedge support 126 and controlled (Fig. 6)

-by the external wedge controlling lever 127 (Fig. 1). Since the ledge 124 is of suflicient extent to overlie the elevating rod for all positions of the wed e, the rod engages with the latter irrespective of the adjustment of the wedge.

The lifting rod treadle 123 is provided (Figs. 1 and 2) with the pawl 130 cooperating with the ratchet 131 so as to maintain the up-pressure on the last without further exertion on the part of the operator. To provide for the automatic release of this uppressure coincidentally with the release of the carriage and the dropping of the toe post, there is provided the treadle releasing arm 132 adapted to be moved to release the pawl from the ratchet. The arm is fixed on the rock shaft 133 (Fig. 2) and is given a releasing movement on movement of the car riage-releasing knee lever 27 which latter, when moved to release the carriage, engages with the finger 134 located back of the knee lever and secured to the rock shaft 133. Movement of the knee lever acts to release the carriage (Fig. 4) through the upright rod 135 connected to throw the bell-crank lever 136 pivoted on the frame of the machine. When thrown, the lever 136 causes a roller 137 to strike the latch 21 and free the same from the catch 22, Fig. 6.-

The last support when elevated and retracted in the heel lasting head is retained in such condition by the pawl 137 (see Figs. 4 and 6) which engages with ratchet teeth 138 on the inside face of the hand wheel 19.

The pawl .is carried on the depending lever 139 which is pivoted between ears 140 on the journal for the hand wheel shaft. The pawl 7 is pressed into engagement by the spring 142 (Fig. 9), but is thrown out of engagement to effect automatic release of the heel band 'and the lowering of the last su port when the roller 143 (Fig. 9) on the lever139 meets the curved top edge of the cam plate 144 fixed to the side of the trackway 6. To provide for the release ofthe hand wheel at any time by the operative independent of the ear riage position, the pawl carrying lever is prolonged at its lower end and carries the portion 145 adapted to be pressed by the knee of the operative at any time to effect the release of the hand wheel.

Turning now to the toe lasting head, the toe lasting devices are mounted upon the wiper support146, which is adjustable by means of the hand wheels 14 and 15 in substantially the same fashion as described with reference to the heel lasting head. The wiper plates 12 (Figs. 21 and 27) are supported upon cam carriers 147, and the latter are given a combined advancing and closingin movement by means of the sliding actuatin bar 148 and wiper lever 13 in the usua manner. Means are provided, however, for removably securing each wiper plate to its carrier so that, while rigidly seated thereon, it may be quickly detached for the substitution of a wiper of different shape. Herein (Figs. 27, 28 and 29) the under face of each cam plate 147 is provided with a recessed shoulder 149 and the rear edge of the wi er late is fashioned to seat against said sioulder and against the flat under side face of the carrier. To removably hold the wiper against itsseat, the lateral edge of the wiper is beveled as at 150 (Fig. 28) and is engaged by the underlying beveled lip 151 of the clamping memher 152, which latter, being pivoted upon the carrier as at 153, may be swung into or out of engagement with the wiper edge.

The clamp also has the shoulder 154 which swings-over the shouldered edge 155 of the carrier, and it acts, therefore, not only to seat the wiper in the recessed shoulder 149, but also to force or wedge the wiper against the adjacent flat face of the carrier. When the clamp is'swun away from the wiper the latter may rea ily be withdrawn from its seat. To force and hold 'theclamp in its clamping position suitable means are provlded, such as the pivoted cam lever 156,

the suitably fashioned end of which is adapt-,

ed to engage the lug 157 projecting from the edge of the wiper carrier. The cam lever when drawn to the position shown locks the clam against the wipet', but movement of its release the clamp lever.

In the disclosed lasting machine the toe lastin head, like the heel lastin head, is provi ed with lasting devices supp ementary or auxiliary to the wiper plates, and, like ree endoutward will act to members 162 which, when the head .is turned down, are-adapted to rest upon the overturned edgesof the stock. These members 162 are preferably formed so that when turned into operative position, they will rest at one portion of their length upon the outturned material on top of the Wipers, and" at another portion press upon the outturned material at the edge of the wiper or even on the insole in front of the wiper edge. The outer longitudinal edge of these auxiliary devicesis preferably beveled or cutaway, as at 162*, Figs. 30 and 31, so that as the wipers move in they may readily wedge under the outturned material and auxiliary lasting devices, lifting the latter if necessary. Of course, if desired these auxiliary lasting devices may be formed'to rest upon the outturned material above or on top of the wipers throughout their length. The arms are pivoted at 163 to the supplemental head,

so that the members 162 are permitted a closing-in movement with the wipers, although normally drawn out against the adjustable stop screws 164 (Fig. 24) by the springs 165 attached each at one end to an arm and at the other end to the head. The work engaging members 162 are removably secured to the-'ends of the fingers 161 by screws 166 and. with interposed shims, so that members of different shapes may be supplied to accommodate different forms of wipers or suit different conditions of use. The work engaging members are herein arranged to increase the frictional hold of the wipers, especially near those advanced por tions which work at the side of the toe, withvTo this end the under or active faces of the work engaging members 162 are so fash-..-

ioned or equipped that when depressed against the overturned edge of the stock above the wipers, as represented in Fig. 30, they act to pinch the stock against the wipers and act to increase the ,draft on the stock by retarding. its slippage over the wiper edges as the latter advance and close in. In

the illustrated instance the .lower edges of the work engaging members are merely roughened, althou h obviously they may be provided with teeth or faced with leather or other friction material according to the-nature of the work and the conditions of use.

The supplemental head is rovided with devices to depressand app y the lasting members 162 to the work. These com rehendf the sliding cap plate 167 controlle by
